Communication method and device, chip, storage medium and program product

Abstract

The invention relates to a communication method and device, a chip, a storage medium and a program product, and the method comprises the steps: receiving indication information indicating a precoding matrix in a target codebook, the precoding matrix and M (Mgt; 2) associating reference signals of the ports, wherein a target codebook comprises a pre-coding matrix with the row number of M; wherein only two rows comprise non-zero elements, the number of columns is 2, and the matrix is a partial phase intervention coding matrix; or, some and only three rows contain non-zero elements, and the matrix is a partial phase pre-coding matrix or a phase pre-coding matrix; or, with and only K (Mgt; k > = 4) rows contain non-zero elements and are partial phase intervention coding matrixes. In the application, the uplink precoding codebook and the indication method are enhanced, so that the uplink enhancement requirement of transmission channel resource pooling is met. The scheme can be applied to communication systems, such as V2X, LTE-V, V2V, Internet of Vehicles, MTC, IoT, LTE-M, M2M, Internet of Things and the like.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a communication method, device, chip, storage medium and program product. Background technique [0002] With the diversified development of mobile Internet, Internet of Things and other services, mobile communication has continuously improved the uploading requirements of massive data, and put forward higher requirements for uplink capacity; the uplink enhancement scheme of transmitting channel resource pooling can be used to improve the Upstream capacity, however, existing protocols only support 2-port and 4-port codebooks, and only non-coherent precoding is supported in the 4-port codebook when only 2 ports are activated for 2-layer precoding, limiting the transmit channel The flexibility of precoding after switching cannot meet the requirement of pooling transmission channel resources, which may cause performance loss; at the same time, when the transmi...

Problems solved by technology

[0002] With the diversified development of mobile Internet, Internet of Things and other services, mobile communication has continuously increased the requirements for uploading massive data, and put forward higher requirements for uplink capacity; the uplink enhancement scheme of transmitting channel resource pooling can be used to improve Uplink capacity, however, the existing protocol only supports 2-port and 4-port codebooks, and when only 2 ports in the 4-port codebook are activated for layer 2 precoding, only non-coherent precoding is supported, which limits the transmission channel The flexibility of precoding after switching cannot meet the requirements of pooling transmission channel resources, which may cause performance loss; at the same time, when transmission channel resources can be pooled, there may be an available transmission channel configuration similar to 3 ports, while 2 ports and 4 ports The Transmitted Precoding Matrix Indicator (TPMI) method of the codebook of the port cannot be applied to the uplink enhancement scheme of transmitting channel resource pooling
